Helm Chart Push Plugin
Helm supports plugin architecture where I can develop my own custom plugin and make use of it or plugin developed by third party and make use of it. The similar way there are n number of plugins available. One such plugin is helm push plugin and that is available over here.
Install Helm Push Plugin
I can install the helm push plugin with a simple command helm plugin install and the GitHub location or the location where I do have the installation files. I can install using Helm plugins.
[email protected]:~/helm_repo_demo$ helm plugin install https://github.com/chartmuseum/helm-push.git Downloading and installing helm-push v0.9.0 … https://github.com/chartmuseum/helm-push/releases/download/v0.9.0/helm-push_0.9.0_linux_amd64.tar.gz Installed plugin: push
Now I can use the command helm plugin list. That’s going to list the plugins installed as a part of this specific helm installation.
[email protected]:~/helm_repo_demo$ helm plugin list NAME VERSION DESCRIPTION push 0.9.0 Push chart package to ChartMuseum
So I do have a push plugin which is going to push the chart package into the ChartMuseum. Now let me go ahead and create a new chart and push the chart using the helm push plugin.
[email protected]:~/helm_repo_demo$ helm create helmpushdemo Creating helmpushdemo
Now we do have this chart. Let me get in to the chart and update the Chart.yaml file.
[email protected]:~/helm_repo_demo/helmpushdemo$ cat Chart.yaml apiVersion: v2 name: helmpushdemo description: Helm push plugin demo type: application version: 0.1.0 appVersion: "1.16.0"
Now, let me go ahead and package this Chart.
[email protected]:~/helm_repo_demo$ helm package helmpushdemo/ Successfully packaged chart and saved it to: /home/ashok/helm_repo_demo/helmpushdemo-0.1.0.tgz
So that’s going to provide me the packaged charts. I can use this package chart or I can directly use the directory as well. So I can use the command helm. I will use helm push command.
[email protected]:~/helm_repo_demo$ helm push helmpushdemo/ mychartmuseumrepo Pushing helmpushdemo-0.1.0.tgz to mychartmuseumrepo… Done.
So that’s going to create the zipped content automatically and push it into the repository. Now I can do an update and check the list of charts available within the repository.
[email protected]:~/helm_repo_demo$ helm repo update Hang tight while we grab the latest from your chart repositories… …Successfully got an update from the "mychartmuseumrepo" chart repository …Successfully got an update from the "stable" chart repository Update Complete. ⎈Happy Helming!⎈ [email protected]:~/helm_repo_demo$ helm search repo mychartmuseumrepo -l NAME CHART VERSION APP VERSION DESCRIPTION mychartmuseumrepo/helmpushdemo 0.1.0 1.16.0 Helm push plugin demo mychartmuseumrepo/myrepo 0.1.0 1.16.0 My another helm chart mychartmuseumrepo/repotest 0.1.1 1.16.0 Repo demo in helm using ChartMuseum to 0.1.1 mychartmuseumrepo/repotest 0.1.0 1.16.0 Repo demo in helm using ChartMuseum
So the advantage of using the push is directly I can mention the chart folder and do a push. I don’t need to do the packaging or I can do the package and move the files, or I can use the curl and pass the packaged chart files using the data binary option into the chart museum using REST API.
So there are multiple ways and these are all different options where I can push the charts into the repository that is the chart museum repository.
